Back on the MAPI: A family of hybrid perovskites (d-MAPI) is presented. Association of PbI₂ with methylammonium (MA⁺) and hydroxyethylammonium (HEA⁺) cations leads to five compounds with the general formula (MA)_1−2.48x(HEA)_3.48x[Pb_1−xI_3−x]. These materials, which can be prepared as thin films, are lead- and iodide-deficient compared to (CH₃NH₃)PbI₃ (MAPI). Keeping a 3D architecture, they are a bridge between 2D hybrid perovskites and MAPI.

缺铅和缺碘（CH3NH3）PbI3（d-MAPI）：2D和3D混合钙钛矿之间的桥梁

回到MAPI上：提出了杂化钙钛矿家族（d -MAPI）。PbI ₂与甲基铵（MA ⁺）和羟乙基铵（HEA ⁺）阳离子的_缔合产生了五种通式（MA）_1-2.48x（HEA）_3.48x [Pb _{1- x} I _{3- x} ]的化合物。与（CH ₃ NH ₃）PbI ₃（MAPI）相比，这些可以薄膜化的材料缺乏铅和碘化物。它们保持3D架构，是2D混合钙钛矿和MAPI之间的桥梁。
